Ivanka Trump's fashion line has been linked to a Chinese factory which was paying its workers only $62 USD a week and violating other Labour standards.

According to a recent audit by watchdog Fair Labour Assocation, the factory's 80 workers were reportedly being paid $62, despite working more than 60 hours, NBC News reports.

Workers were making clothing for New York-based label G-III, which has the exclusive rights to Trump's label. However, it is not clear whether Trump's clothing was being made at the time of the audit inspection last October.

The report released this week does not specifically mention the factory or the Trump clothing line. The label also has partnerships with Calvin Klein, Donna Karan, Kenneth Cole and Karl Lagerfield, according to its website.

According to the association, auditors found two-dozen violations of the UN International Labour Organisation, including that overtime work exceeded the legally required limit of 36 hours per month. Workers instead had accumulated between 42 and 82 hours per month, the association found.

It also found workers were taking home between $255 to $284 USD each month but did not find a violation of failing to pay minimum wages.

In a statement to NBC News, G-III said the issues had or were in the process of being corrected. It added that its factories were "routinely audited" by its own experienced team, as well as third-party groups like the Fair Labour Association.

The audit report also comes the same week as Trump is in Germany to discuss global entrepreneurship and empowerment.

"We can add billions to the global economy by creating an enabling environment, increasing women’s labour force participation and business ownership, and improving the productivity of their work," she wrote in a Financial Times essay on Monday.

Trump's fashion company did not respond to request for comment. Trump stepped down from her management role within the company in March, in order to take an unpaid advisory role in the White House.

The clothing line has been targeted by anti-Trump activists and was dropped by luxury department store chain Nordstorm, who said it was a "poor performer".

However, according to G-III's annual report, the brand accumulated a $17.9 million increase in net sales in 2016.
